SASH-FASTENER.

SFECIPICATION forming part of Letters Patent No. 318,576, dated May 26,1885.

Application filed January 15, 1885.

To all whom it may concern.-

Be it known that 1, CHARLES XV. NIDA, of New York city, in the countyand State of New York, have invented a new and useful Improvement inSash-Fasteners, of which the following is afull, clear, and exactdescription.

The object of my invention is to furnish a reliable sash-fastener, whichwill lock the upper and lower sashes of a window by one operation in aclosed or open position, and which cannot be unfastened by introducing aknife or similar contrivance between the sashes from outside the window,and that can be applied to any window without cutting or injuring thesame in any way, and that shall be simple in construction, ornamental inappearance, effective in operation, and can be applied or attachedwithout the aid of skilled labor.

My invention relates to a locking device for window-sashes wherein theprojection or throw of a slotted bolt locks both the upper and lowersashes at the same time, and locks the sashes in an open or closedposition by means which will be hereinafter fully described and claimed.

Reference is to be had to the accompanying drawings, forming part ofthis specification, in which similar letters of reference indicatecorresponding parts in all the figures.

Referring to the drawings, Figure 1 is a horizontal section through theupper sash of the window, parts being broken away, showing plan view ofsash-fastener as it appears applied on the meeting-rail of lower sash.Fig. 2 is a horizontal section through upper sash, with the casing ofsash-fastening bolt in section, showing my sash-fastener in a lockedposition. Fig. 3 is a front view, partly in section, parts of upper andlowersashes being broken away, showing the racks and fastener attachedto sashes and easing. Fig. 4 is a bottom plan view of my doubly-actingbolt or fastener. Fig. 5 is a side view of cam-spindle, to whichactuating-lever is pivoted and used to project and retract the bolt orfastener. Fig. 6 is a detail of an attachment to bolt. Fig. 7 is adetail of a spring placed under actuating-lever. Fig. 8 is a detailshowing front view of one of the racks.

A is a bolt with a slot or opening, a, formed in it about midway of itslength, said slot receiving the cam by whichbolt is projected or re- 7(No model.)

tracted by the cam working against the faces of said opening. Bolt Aisalso provided with a tail-piece, b, which acts as a guide to the slidingmovement of bolt by passing through a slot in boltcasing. Bolt A is alsoforked at its front end, or rather has two angular projections, c, atits forward end, said angular projections being at right angles to eachother, and are both slotted to receive and hold in said slots pivotedcatches or pawls (1, one of said pawls in the slot of each projection c.Said pawls or catches d engage with racks 0 when bolt is shot. The rackse are attached one to the stile of upper sash and extending frommeetingrail upwardly ten or twelve inches, and the other to the windowjanib or casing close to the parting-strip, and extending from about topof meeting-rail upwardly about six or eight inches. These racks are thinstrips of metal provided with necessary screw-holes for attachment, anda number of equidistant perforations, preferably rectangular, to bestamped out of or otherwise formed in said metallic strips.

The pawls d are pivoted, as before stated, in the slotted projections cof front portion of bolt A in such a manner that a forward movement ofbolt A will cause the teeth f on their front or outer edges to engage orenter some of the perforations in both racks at the same time and by thesame movement, the teeth f being far enough apart to admit eachindividual tooth entering two succeeding holes or perforations in saidracks; or, if only one of the teeth f should enter, the catches or pawls(2 being centrally pivoted and swinging freely on said pivot, theslightest movement given to sash would cause the other tooth or forwardedge of catches (Z to enter next perforation in rack and cause it tofirmly bind therein; or, if by mischance or carelessness the teeth fshould not enter any of the perforations in either rack by not being inline with said perforations when bolt is shot, so that the teeth f willrest on solid portion of rack, the slightest vertical movement of sasheswill cause the catch (1 to swing on its pivot by the friction of solidportion of rack against the teeth f until either of the teeth f meetsaperforation, in which it will be forced to enter and bind. To preventcatches d from swinging back wardly too far in such a movement I formtW':

additional-teeth, g, on the rear edges of said catches, at top andbottom of same, which, while allowing a slight rotary movement tocatches (I, will bring up solidly against the body of bolt A, directlybehind the slots in which said catches d are pivoted, as soon as one ofthe teeth f has entered a perforation, and thus lock the sashes, even ifbut one of the teeth f in each catch has entered the respective racks.

From the above it will be seen that my fastener will automatically lockthe sashes if any attempt to open the window from the outside is made,even when not set properly.

B is a spindle on which is formed a cam, O, for moving the bolt A, abottom plate, D, for supporting bolt or fastener A, and a slotted apexto receivethe pivoted actuating-lever E. Said spindle is upwardlyintroduced through slot ain boltA until its bottom plate,D,strikesagainst the bottom face of bolt A, the cam O in slot at and the spindleproper passing upwardly through a neck, h, formed on boltcasing F andprojecting therefrom. The pin 2' passes through actuating-lever E andthe slotted apex of spindle B, and in connection with a. spring, j,placed between top of said neck of casing and the bottom edge of leverE, holds all in proper position.

The casing F is provided with a slot, 19, for the tail-piece b of boltA, and also a slot, 0, for the front portion of bolt- A, and a number ofratchet-teeth, j", are arranged in a semicircle (n one-half of the topedge of the top plate of said casing. Said ratchet-teeth are to receiveand hold the heel 70, formed on the rear portion of the pivotedactuatinglever E to lock the same. I

The spring j before mentioned has two semicircular openings of a sizesufficient to allow spring-to be slipped over the slotted apex ofspindle B, and the solid portion or bridge between the openings to restin bottom of slot in said apex of spindle B. The rear end of spring willrest under a shoulder, m, in lower edge of lever E, and the forward endof spring will be bent up and forked or notched to receive bottom edgeof said lever E, so as to exert a constant upward pressure against leverE and press the heel is of lever E into one of the ratchet-teeth jformed on bolt-casing.

The lever E is provided also with a button on the forward part of itstop edge. By pressing on this button the forward part ofcentrally-pivoted leverE and spring 3' is depressed and the heel is oflever Eraised out of ratchetteeth j". The heel 7c of lever E being nowdisconnected from ratchet-teeth may be swung around in a semicircle, asshown by dotted lines in Fig. 1, revolving its attached cam O and bottomplate, D,and causing the bolt A to be shot or retracted at will. Thebutton being released the spring j will raise front end of lever E andcause the heel is to drop into one of the notches or ratchet-teeth j andlock bolt A in any desired position.

To put the fastener together, the bolt A is slipped in casing F,tail-piece first, through slot 0 until tail-piece 1) projects throughits own slot 1). The spindle B is then introduced upwardly through slotin bolt A until the bottom or supporting-plate,D,meets bottom face ofbolt A, the spindle B proper passing up through neck h of easing F andprojecting from top of neck 72. The spring j is now placed over slottedapex of spindle B, as before described, lever E inserted in slotted apexof spindle B, and the forward portion of bottom edge of lever E restingin notched forward end of spring and the pivot-pin 11 being placedthrough slotted apex of spindle B, and lever E fastens all together.

The slot p, through which tail-piece b of bolt A passes, is made widerthan tail-piece b, to allow of a slight side movement of forward portionof bolt in case there should be a difference in the dimensions ofvarious windows, so that the catches f can enter the racks onwindow-stile and window-casing.

The fastener should be attached on meetingrail of lower sash, so that aline drawn at an angle of about ninety degrees from the inner corner ofparting-strip will pass centrally through the bolt A, and theprojections 0 will stand at right angles to lines of sash, asrepresented in drawings. By this arrangement it is obvious that a windowcan be left partly open at top and bottom for ventilation, &c., and thesashes securely locked in said open position, so that an outsider couldnot enter, and it will, also, securely lock the sashes when both areclosed,or one closed and one open.

The rack fastened to the window-casing, being made thin, gives plenty ofplay to the movement of lower sash.

It is evident that the catches or pawls d IOC might be dispensed withand the angular projections 0 made to enter perforations in racks, ifproper care was exercised in shooting the bolt to see that they bothentered a perforation in either rack; but to guard against any Suchcarelessness I have thought it better to add the pawls d, toautomatically lock the sashes, even if fastener is not properly set, byany attempt to move either sash from outside the window.

Having thus described my invention, I claim as new and desire to secureby Letters Patent- 1. In a sash-fastener, the combination, with acasing, of a bolt in said casing provided with an aperture, a spindlearranged to turn in the casing and provided on-its lower end with a camand a plate below the cam, and a lever pivoted in the apex of saidspindle and adapted to turn the spindle, substantially as herein shownand described.

2. In a sash-fastener, the combination, with the casing D, of thespindle B, the bolt A, the lever E, pivoted in the top of spindle B, anda spring, j, placed below the lever on said spindle, substantially asherein shown and described.
